A hospital is trying to cut down on emergency room wait times. It is interested in the amount of time patients must wait before being called back to be examined. An investigation
committee randomly surveyed 100 patients. The sample mean was 1.6 hours with a sample standard deviation of 0.5 hours.
Using a calculator, determine the confidence interval for a = 0.05.
A. (1.502 , 1.698)
B. (1.205 , 1.986)
C.(1.5008 , 1.6992)
D. (1.8005, 1.9962)
